Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 7,259,765, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 7,259,765 | |
| -1 | -7,259,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,259,765.
Example:
1 x 7,259,765 = 7,259,765
and
-1 x -7,259,765 = 7,259,765
Notice both answers equal 7,259,765
With that explanation out of the way, let's continue. Next, we take the number 7,259,765 and divide it by 2:
7,259,765 ÷ 2 = 3,629,882.5
If the quotient is a whole number, then 2 and 3,629,882.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 7,259,765 | |
| -1 | -7,259,765 |
Now, we try dividing 7,259,765 by 3:
7,259,765 ÷ 3 = 2,419,921.6667
If the quotient is a whole number, then 3 and 2,419,921.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 7,259,765 | |
| -1 | -7,259,765 |
Let's try dividing by 4:
7,259,765 ÷ 4 = 1,814,941.25
If the quotient is a whole number, then 4 and 1,814,941.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 7,259,765 | |
| -1 | 7,259,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 223 | 383 | 1,115 | 1,915 | 3,791 | 6,511 | 18,955 | 32,555 | 85,409 | 427,045 | 1,451,953 | 7,259,765 |
| -1 | -5 | -17 | -85 | -223 | -383 | -1,115 | -1,915 | -3,791 | -6,511 | -18,955 | -32,555 | -85,409 | -427,045 | -1,451,953 | -7,259,765 |
